Horton the Elephant struggles to protect a microscopic community from his neighbors who refuse to believe it exists.
Rated G however mild frightening scene at end of movie

With their impeccable timing and incredibly expressive voices, Carrey and Carell are the perfect combo to play Horton and the Mayor. They capture their characters' sense of awe and insecurity. The film expands the book's character pool to create a huge family for the Mayor: He has a wife (Amy Poehler) and 96 daughters. Also, Jo Jo (Jesse McCartney) is now the Mayor's loner, misunderstood son instead of a random Who. There are other differences between the original text and the film, but most work just fine to pad the story.

What's especially refreshing is that, by keeping the adaptation animated, there are no costumed actors to distract from the story's positive message. Horton firmly keeps the focus on his promise to protect the Whos because he believes in the inherent value of all beings. That's a powerful -- and difficult -- concept for very young kids to grasp, but somehow Dr. Seuss (channeled by this big-studio production) makes the lesson both approachable and very entertaining.
